BAPI-Com, Two-wire Multifunction Sensor
Features & Options
- Power and Communication on Just Two Wires
- Available with Temperature Setpoint and Optional Override, Display and %RH Sensing
- Thermistor, Voltage, Resistance or Dry Contact Outputs
- Up to 500 Foot Wire Runs — Perfect for Existing Wires
Many existing buildings have two wire sensors that lack the features people expect in today’s sophisticated systems. The BAPI-Com uses those existing two wires and offers the owner a full function sensor with temperature setpoint, occupant override, an optional easy-to-read display and optional %RH sensing. This retrofit sensor can update old systems to a new look without pulling new wire or disrupting the occupants while saving on labor.
The sensors are powered and communicate over two wires to a Communication Output Module for use by a BAS system. The outputs are configurable as a thermistor, voltage, resistance or dry contact override output. The sensor is powered by the Communication Output Module which itself is supplied by any 24VDC/VAC source.

Dew Point Sensor
Features & Options
- Accurate Dew Point and Dry Bulb Temperature in One Unit
- ±1.8°F (1°C) Dew Point Accuracy for the Normal Range
- Multiple Analog Outputs, 0 to 5VDC or 0 to 10VDC
- No Installation Calibration or Recalibration Required
The green revolution is increasing the use of chilled beams and chilled ceilings in commercial buildings. Chilled water is pumped through hollow beams or special hollow ceiling tiles. Radiation cools the space eliminating air handlers, VAV boxes, fan-coil units and the energy to run them.
The temperature of the chilled water has to be regulated above the space’s air dew point temperature. If the beam or ceiling temperature is below the space’s dew point, they will “sweat”, causing mold and dripping water.
BAPI’s Dew Point Sensor is an easy and economical way to measure the dew point temperature. The unit is available with an optional display, temperature setpoint slider and an occupant override pushbutton. The large format display allows you to easily read Dew Point Temperature and Dry Bulb Temperature. The display alternates between these values and is field adjustable between °F or °C. One or both of the displayed values may be easily turned on or off by an HVAC technician.
